Dear expert,
I have to add one column "ID" in postgres table which will generate Auto Increment<http://www.davidghedini.com/pg/entry/postgresql_auto_increment>ed number .
Example:
Suppose I have five records and if I insert 1 new record It should auto generate 6.
If I truncate the same table and then again insert rows should start with 1 in "ID" column.
Regards,
Dinesh Chandra
